Granted: 1991-01-22
Abstract: Abstract of the Disclosure If ultra-high-molecular-weight polyethylene having an intrinsic viscosity (?) of at least 5 d?/g is grafted with a silane compound in the presence of a radical initiator and extrusion-molded and the extrudate is impregnated with a silanol condensation catalyst after or during drawing and is then exposed to water to effect crosslinking, there is obtained a novel molecularly oriented molded article in which increase of the melting temperature, which is not observed in conventional draw-molded or crosslinked molded articles of polyethylene, can be attained, and even if this molecularly oriented molded article is exposed to a temperature of 180°C for 10 minutes, the molded article is not fused but the shape is retained and even after this heat history, a high strength retention ratio can be maintained.  In this draw-molded article, the adhesiveness and creep resistance are prominently improved while high elastic modulus and high tensile strength inherent to a draw-molded article of ultra-high-molecular-weight polyethylene are retained.

Abstract: APPARATUS FOR PRODUCING A SPRAY OF DROPLETS OF A LIQUID                  ABSTRACT    Apparatus, for example an inhaler, is disclosed in which a spray is formed electrostatically from an outlet 6 to achieve uniform droplet size.  The spray is then discharged for its intended use - in the example inhaling. The spray is discharged completely by corona produced by a sharp discharge electrode 16 which is charged to a polarity opposite that of the liquid.  In order to prevent the corona from spoiling the formation of the spray itself, the liquid at the outlet 6 is protected by a neutral shield electrode 8.  The spray issues through a hole 14 in the shield electrode.  The hole is sufficiently small to prevent corona getting through, yet sufficiently large to allow the spray through.

Granted: 1991-07-02
Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus for correcting the undeflected resting position of an electron beam which has been displaced from its previous resting position because of physical or positional changes in elements of the electron gun which is generating the electron beam.  The elec-tron beam is directed towards a detector which determines the direction and amplitude of the deviation along mutually perpendicular axes of the point of impingement of the electron beam from a given reference point. The signals generated by the detector, in cooperation with a computer-controlled deflection system of the electron gun, cause the beam to be displaced in a series of iterative steps to the reference point.  The distance and direction of the beam from its resting position to the reference point is maintained in the memory of the computer.          .

Title: Electronic fuel injection circuit with altitude compensation
Inventor: STAERZL RICHARD E
IPC: F02D41/32
Filed: 1987-12-22
Granted: 1992-07-21
Abstract: ABSTRACT OF THE DISCLOSURE          A resistance switching circuit is toggled immediately prior to cranking but subsequent to power application by the output of a manifold absolute pressure sensor effectively responding to ambient atmospheric pressure as indicative of altitude.  The switching circuit is connected in series with the resistance element of the potentiometer which serves as the throttle control and alters the transfer characteristic of the control circuit.  The gain of the system is such that the output operational amplifier saturates at an intermediate throttle setting such that the response for slow throttle is y=nx over the entire range of manifold pressure, while for fast throttle the response is y=nx for low manifold pressure and changes to y=mx+b for higher manifold pressure.

Granted: 1992-01-07
Abstract: PAGER BASED INFORMATION SYSTEM                 ABSTRACT OF THE DISCLOSURE A pager based information system is used to transmit both conventional private messages (using unique pager IDs) and two types of unconventional multi-recipient (M-R) messages (using database IDs and group IDs), all using the conventional POCSAG pager transmission format.          Operation of the pager is software controlled through the use of a microprocessor and a RAM; auxiliary chips are not needed because of the relatively slow transmission speeds.  Authority to receive the M-R messages is provided at the time of manufacture (database IDs) or via broadcasts (group IDs).  Database type M-R messages are stored in the pager RAM in a hierarchial or tree structure.  The software controlled pagers permit the over-the-air modification of the operation of selected pagers, such as the addition or deletion of group IDs and the change in the tree structure of the storage area for the database messages.  The pager includes a real time pager clock which is update by pairs of broadcast time messages, the second having a time correction for the first.

Abstract: The process makes calcium sulfate alpha-hemihydrate from finely divided calcium sulfate dihydrate by transforming the calcium sulfate dihydrate in the presence of saturated steam. A molded body is formed from the calcium sulfate dihydrate which has a plurality of pores having a pore volume amounting to 15 to 60 % by volume of the total volume of the entire molded body. More than 5 % by volume of the pore volume contains air. The molded body is fed to the autoclave. In the presence of a sufficient water quantity in the pores the crystal habit and the crystal growth of the calcium sulfate alpha-hemihydrate crystals which grow in an aqueous solution phase are controlled by a process temperature in the range between 110° to 180°C by the pressure of the process atmosphere in the autoclave. The molded body is removed from the autoclave after recrystallization transformation and delivered for use. Key products of this process and their derivatives are also described.

Title: Process for removing or transforming lignin
Inventor: CALL HANS-PETER

Filed: 1988-06-30
Granted: 1995-06-27
Abstract: The invention relates to a process and an apparatus capable of removing and/or transforming lignin or its degradation products present in material containing lignocellulose.  In the present process, a redox potential is set between 200 and 500 mV by the addition of oxidizing agents and/or reducing agents and/or salts and/or phenolic compounds to an acid aqueous solution which contains lignitic raw materials.  The lignin degrading reaction and its attendant simultaneous bleaching effect is initiated by the addition of enzymes, microorganisms, animal or plant cells.  Continuous stirring allows the reaction to be maintained for several hours at a value that fluctuates about a constant redox potential value, and a constant temperature.
